MP 128.0 - Partridge Siding The Dispatcher has scheduled a more conventional meet here at Partridge Siding. A westbound coal drag is in the hole waiting for No. 2 as it climbs eastward. Partridge Siding is named after Seth Partride, a CPR engineer who saved several lives by warning the sleeping occupants of the old Yoho station just before a mud slide demolished it. (15 of 21)
